Recently Bina asked me if I will be in a relationship with a guy I am currently "meet" regulary. I told her that this is just a sex thing and on her shy question what makes him special I just show her a distance with my finger. She did not believe me so I asked her to watch us from the other side of the roof-deck from the library room. She should switch off the light and enjoy the show.
Well yesterday he showed up again and Bina was around. When we went to my room I smiled at her and she got it. I sucked him off and later let myself get fucked against the window. It was a huge show. But I think it was fun for all of us. He did not get it so ;)
